Fix "Invalid mode found: /usr/lib64/firefox/firefox.sh"

After several hours of debugging on IRC and flooding paste.opensuse.org ;-)
I finally found the reason - reading(!) from log_dict with a wrong 
key caused the creation of that strange mode in log_dict.keys().

While finding that bug was very hard, the fix is easy - just replace 
"profile" with "aamode". (That probably makes one char per hour of 
debugging...)

To improve that ratio, also add a warning to common.py so that this 
interesting[tm] behaviour of hasher() is at least documented.
